THE HAMPDEN cLoNoUnnY oorrnaivr'mnsmiviirnii. or'lvrnnsouimn, AUSTRALIA,

To all whom it may concerm Be it known that I, ERLE SrAFroRn I-IUNr LEY,general manager of the Hampden Cloncurry Copper Mines Limited, ofFriezland, in the State of Queensland, Commonwealth of Australia,subject of the King ofGreat Britain, residing at Friezland, in'the Stateof Queensland, Commonwealth of Australia, have invented certain new anduseful Imfollowing is a specification.

This invention relates to an improved gas provements in Gas-Producers,*of wl -ichfthef 'producer for the generation of gaseous fuel and refersmore particularly to a producer for the generation of gas for powerpurposes from wood, charcoal, coke, coal or other like suitablefuel.

The object of this invention is to provide a producer in which gas isgenerated for use in the production of power in a cheaper and moreefficient manner than heretofore.

This invention comprises a vertical chamber having a feed at the top forthe introduction of the primary fuel, a series of twyers for-theintroduction of free air underneath the primary fuel, an exit for thegas beneath the said twyers, a grate at the bottom and means for theintroduction of air and steambeneath the said grate. By this arrangementan incandescent zone is pro vided underneath the primary fuel and abovethe gas exit and another incandescent zone above the grate and beneaththe gas exit and the 'gas is withdrawn from the producer at about thecenter of the body of fuel so that there are two distinct incandescentzones, one above the gas outlet and the other below the same. Provisionis made 7 for the introduction of steam. into the feed chamber with theprimary fuel which prevents the incandescent zone opposite the aforesaidtwyers from rising.

This invention will now be more fully described aided by a reference tothe accompanying sheet of drawings in which- Figure 1 is a longitudinalsectional elevation of a producer taken on line 2-2 of Fig. 2 while Fig.2 is a plan of the same.

Fig. 8 is a cross sectional elevation taken A gas producer constructedaccording to this invention comprises a vertical chamber A constructedpreferably of sheet metal lined with firebrick or other fire resistingail awn e. l.

material A. This-vertical chamber A is furnished l with" i a-[semicircular or arched dome or cover B at its top having suitable feeddoor or doors B for the supply of fuel.* "The main body ofthejproducerisconstricted at or about the center A where- :by two distinotfchambersare afforded the --upp'er A being adapted for the combustion of theprimary fuel, and the lower A? for the combustion of the fixed carbonand secondary fuel after having passed through the upper chamber. At thebottom of the upper rectangular chamber A are provided means for theintroduction of air underneath the primary fuel which comprise a seriesof twyers C arranged in the walls of the said chamber immediately abovethe constriction A while a series of air inlets or twyers C are alsoarranged around the said constriction. These inlets or twyers may befurnished with controlling valves adapted to regulate the supply of airtherethrough. In the bottom of the lower cylindrical chamber A is fitteda fire grate D beneath which are arranged openings E for the admissionof air under the incandescent fuel and these openings E may be furnishedwith valves for controlling the admission of air. These openings E arealso adapted for removing the ashes (if any) from beneath the grate D.Above the grate D are arranged poking holes D. Just below theconstriction A that is to say between the two zones of combustion isprovided an outlet F for the gaseous fuel. Within the said chamber A andopposite to the said outlet F is an inverted U-shaped bridge Fconstructed of firebrick or fire clay or cast iron (water jacketed ifnecessary). The said gas outlet F communicates with a chamber Gr withinwhich heating pipes are provided for the vaporization of water and fromwhich the gas passes to the necessary scrubbers, coolers and cleanersand thence to the gasometers or otherwise as may be desired. Steam pipesJ leadwhere the admission of air through the twyers O C causes it to bepartly converted into produeer'gas and partly into charcoal pa'ssesthenee 'toath'escrubbers, cleaners, and coolers for use as -requ1red.

I- claim A,.gas ;pro ilueer, eomprlsing 1n eomb1nation, a yertiealchamber having a eonstrloti'on dividing the same into upper" and lowereompartmenta a-eover for-said chamber-provided with feed openings; aseries of twyers introduelng alr lnto the upper compartment,

a second series of tvifyers introducing a'ifat 'said "eonstrictro'n; a"gas outlet, an inverted U-shaped bridge within the lower chamberopposite to and communicating with said outlet, a grate at the lowerpart of said lower chamber, means for admitting"air beneath-said-grate,-a vaporizer, and a steam pipe leading from said Vaporizer and sup plyingsteam into said ehamber -at the top and bottom thereof.

In testimohywhereof I have aflixed any Signature in preseneelof twowitnesses.
